Thanks. Using FL Studio. No MIDI out on Oxygen. Don't have a USB cablewith the Doepfer, but it does have a USB connection. (second hand so guess there should be, will a generic one work?).

At the moment I have a MIDI In from Dark Energy to MIDI Out of MIDI Interface. I have my Oxygen connected to FL Studio via USB. The MIDI Interface is sending MIDI Out from key presses of the Oxygen, but still no sound. My set-up

Appreciate the response, realise this is bread and butter stuff but i just really want to hear the thing!
